AUTOMATIC CENTRIFUGAL DISCHARGING-MACHINE.

Application led July 27, 1914. Serial No. 853,323.

an automatic machine of this character which will entirely dispense with hand.

labor in discharging the'centrifugals, vand lit is so constructed and arranged that the workman can perform the work without making it necessary for him to bend over into the `basket of the machine, since the paddles or. blades, which are' used to remove and discharge the sugar, are so connected with a vertically movable piston rod that.

the operation of lowering the blades, and doing thel work -i'sall accomplished by the machinery, and controlled in a most eilicient manner by! the operator.

It also further provides a means whereby the speed of the cutting is automatically regulated, so that it will be impossible, by any carelessness on the partof the operator,

-to wear out the cutting blades unnecessarily,

or to cause any damage to the revolving basket during the discharge operation.

The invention consists of a verticallydisposed cylinder with a piston rod therein, and suitable stufling boxes, soarranged that it is double acting, and designed to be operated by either air. or water, and the J piston rod carries` at its-lower end the cutting blade, or paddle which is designed to operate within the basket of the machine, and this blade or paddle is so mounted on the piston that it is capable vof having a slight rotary movement, whereby the blade may be withdrawn and cleared of the basket when in operation, by means of which the blade when lowered into the basket will automatically set itself inposition to perform the required work. As it is necessaryin mechanism of this characterto'cut the sugar at the perimeter of the basket at different speeds,

as the blade descends, provision is made whereby the speed is automatically changed to suit the conditions, all of which will now be set forth in detail.

` In the accompanying drawings, Figure 1 is a'front elevation of the discharging machine. F ig. 2 is a vertical section of the cylinder and piston for the'dischargingmachine..- Fig. 3 isa top view of a centrifugal machine showing .the relative position ofthe discharge mechanism. Fig. 4 is a horizontal Asectlon of the upper'` end'of the piston rod,

and cylinder on line 4 of Fig. 6. Fig. -5 is' a 'horizontal section of the cylinder on line 5 of Fig. 6. Fig..6 is a vertical section of portions of the cylinder and piston rod. Fig. 7is a view of the lower side-of the disk at the. end of the cylinder. Fig. 8 is lan'edge view of the disk, and Fig. 9 is a sidepview of the upper end o f the piston rod, partly insection.

In constructing my invention` it is my I desire to apply it to any type of centrifugal machine, one form of this machine beingshown bythe main cylindrical body 10, which has withinit the usual basket 1l, provided with the enlarged upper opening 12. The maincylindrical body 10'has a :sol

circular opening 13 through its upper end,

,and mounted on the body is the base flange 14 of an upwardly projecting bracket 15,

lwhich .is designed-t0 carry the cylinder and operatlng piston rod of the discharging mechamsm. v l

A vertical cylinder 16, flanged at its lower end, as shown at 17, is secured by bolts or. .otherwise to the'top of thel bracket ange 18, and integral with the flange .18, and projecting downwardly therefrom is a tubular extension 19, provided at its lower end with an annular channel to receive therein packingmaterial 20, which is held in position within the channel, and4 against the piston rod 21 by means of the conventional stuiling box 22. The upper end of thiscylinder 16 4has a suitable removable head 23, and at each end ofthe cylinder is a boss for a pipe connection as at 24, and a pipe 25 connects with the opposite ends of the cylinder, this pipe having an intermediate four-'way valve 26, provided with a lever 27, and so operatively connected up that when steam or. other compressed fluid enters the supply port 28,

pipe 29, as is usual with valves of this ty e. The principal feature of this inventlon the fluid will enter one end of the vcylinder and be discharged from the other end of the' cylinder through the discharge A resides in the construction and arrangement "f the piston rod 21 within the `cylinder 16;

.of the piston rod. To accomplish this I' provide thel upper end of the tubular piston rod 21 with a disk 31 of hardened steel, this' disk being.,held 4in position by a cap -32 which is flanged and threaded so that it will screw down and firmly hold the disk in position. For the purpose of preventing the` disk from turning, it is provided with a pair of downwardly projecting lugs 33 on opposite sides, these lugs being designed vto enter l notches 34 in the end of the piston rod 21.

It will be noticed that the upper end of the piston rod has a packing ring 35 attached thereto which serves as a piston, and to provide a means for preventing the pis- `ton from turning a groove 36 is provided in the 'wall of the piston rod, andy a corresponding groove in the piston to receive a ey. l

The disk 31 has a square hole 37, and the head of the cap has 'a round hole 38, the ob.

ject of the square'hole being to receive therein a bar 39 square incross section, which bar projects down into the tubular piston. The upper end of this bar 39 is secured to the head 23 of the cylinder, in such a manner that it may be revolubly adjusted a limited distance, this adjustment being made by a screw 40, which passes through a flange 41 integral with )the bar. The end of the bar 39 projects through the cylinder head, and its squared end is thereby exposed to permit of the bar to be turned by a wrench and thus set'it in anydesired position by the adjusting screw 40.

Near th upper eiid the bar 89 has an eighth twist, as shown at 42, soithat when the piston rod 'moves up or down, -the disk through which the bar passes will follow the twist and thus cause the piston' rod to turn and thereby swing the shoe at its lower end clear of the margin of the basket.

, The' location of the twist in the bar is such that the bar is rotated during the downward movement of the piston rod at that point where the cutting edge of the shoe has just passed down below the marginal opening of the basket, so that the cutting point of the shoe will follow the upper inclined wall 44 of the basket and when the piston rod moves upwardly the rotation of the piston will also permit the cutting point uses, w

the upper inclinedv wall.y

It 1s obvious that while this invention has been described as relating particularly lto centrifugal machines for cutting and 'discharging sugar, the 'elementary components -of the invention, asset'forth herein, may

also be applied to any character of machine 'for handling other products and for other ithout departing from the spiritof my invention. j What I `claim 1s:

In a discharging device for centrifuy gals, a vertically disposed cylinder, a'piston rod extending through the same and carrying a cutting and discharging shoe at its lower l end, means for vertically vmoving sald piston rod in either direction, means for partially rotating said piston rod during its' movement, said last mentionedmeans including a disk through which the piston rod passes to limit its rotary .movement 2. In 'a discharging device for centrifugals, a centrifugal separator, having in c0111- bination therewlth and attached .thereto al vertically movable cutting and discharging shoe, said shoe adapted, to be lowered into the centrifugal and automatically swung into operative position during its downward movement, and swung clear of thecentrifugal when saidshoe is moved vertically up- A Ward.
